[57] ABSTRACT A calendar construction in which a lobed, resilientlyflexible calendar-bearing annular disk is mounted for rotation upon apedestal-supported drum and retained on the drum by a radially narrowlip which enables selective removal and replacement of the disk byforcing the disk over the lip. The disk may be indexed to a selectedposition where a portion of the calendar is at a predetermined viewinglocation, and abutments engage a lobe to retain the disk at thatposition. A relatively large display surface is provided at the viewableend of the drum for displaying advertising copy, other information ordecorative effects.

13 Claims, 4 Drawing Figures CALENDAR DISPLAY CONSTRUCTION WITH INDEXINGCALENDAR BEARING MEMBER The present invention relates generally tocalendars and pertains, more specifically, to calendars of the typehaving a readily replaceable calendar-bearing member carried by acalendar frame which is aesthetically pleasing and is especially wellsuited to displaying advertising copy, other information or decorativeeffects.

Calendars, and especially calendar stands and holders, have becomepopular as advertising premiums which are distributed by individuals,firms or companies and the like to customers and friends. These calendarstands and holders, aside from carrying calendars, often serve asvehicles for advertising literature. Since it is the invention of thedistributor of such calendars to have the recipient display the calendarat a prominent location and keep the calendar for a long period of time,so that the distributors advertising message is constantly before therecipient for the duration of that period, it would be advantageous tohave available a calendar construction which is aesthetically pleasingand will bear calendar information which is easily kept up to date for along period of time so as to encourage the recipient to keep thecalendar.

It is therefore an important object of the invention to provide acalendar construction which is aesthetically pleasing and in whichcalendar information is easily and inexpensively kept up to date.

Another object of the invention is to provide a calendar constructionwhich may be packaged in a compact, flat configuration for ease ofmailing or distribution by other means and which readily may be erectedfor use.

Still another object of the invention is to provide a calendarconstruction of the type described above which is compact, yet carrieslegible long-term calendar information which is easily and inexpensivelyreplaced for extending the term of the calendar information.

A further object of the invention is to provide a calendar constructionhaving adequate, conspicious display surfaces for carrying advertisingcopy, other information or decorative effects.

A still further object of the invention is to provide a calendarconstruction in which a calendar holder or stand is of unitaryconstruction and which may be fabricated in large quantities at minimumexpense.

The above objects, as well as still further objects and advantages, areattained by the invention which may be described as a calendarconstruction for displaying a selected calendar interval at apredetermined viewing location, the calendar construction comprising aframe, drum means projecting from the frame, a calendarbearing memberincluding an obverse surface extending in a direction transverse to thedirection in which the drum means projects and carrying a plurality ofCalendar intervals thereon, the member having an aperture complementaryto the drum means such that the member may be rotated selectively uponthe drum means to index the member to a selected position for locatingthe selected calendar interval at the viewing location, and a lipintegral with the drum means and extending laterally therefrom tooverlap the calendarbearing member along at least a portion of theperimeter of the aperture to retain the member upon the drum meansbetween the frame and the top, the relative dimensions of the lip andthe aperture and the relative flexibility of the lip and thecalendar-bearing member at the perimeter of the aperture being such thatthe member selectively may be forced over the lip to remove and replacethe calendar-bearing member.

The invention will be more fully understood, while still further objectsand advantages will become apparent, in the following description of anembodiment of the invention illustrated in the accompanying drawing, inwhich:

FIG. 1 is a front perspective view of a calendar constructed inaccordance with the invention;

FIG. 2 is a front elevational view of the calendar with thecalendar-bearing member separated from the calendar frame;

FIG. 3 is a side elevational view of the calendar of FIG. 2; and

FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 1.

Referring now to the drawing, and especially to FIG. 1 thereof, acalendar constructed in accordance with the invention is illustratedgenerally at 10. Calendar 10 is a desk calendar and has a frame 12 whichincludes a base 14 extending generally horizontally for supporting theframe upon a desk top (not shown), and a pedestal 16 extending upwardlywith respect to the base 14 for supporting a calendar-bearing membershown in the form of a disk 20. Disk 20 includes an obverse surface 22upon which there is printed, or otherwise inscribed, a plurality ofcalendar intervals 24. In this instance, each interval 24 comprises amonth of a calendar year, and each consecutive month of the calendaryear appears in sequence around the disk 20.

Turning now to FIGS. 2 through 4, as well as to FIG. 1, disk 20 has anannular configuration which includes an outer periphery 26 and an innercircular aperture 28. The pedestal 16 is provided with a drum meansshown in the form of a drum 30 projecting generally perpendicular to thepedestal l6 and including a drum surface 32 having an outside diametercomplementary to the inside diameter of the aperture 28 of the disk 20so that the disk may be journaled for rotation upon the drum 30 with theobverse surface 22 transverse to the drum 30. Disk 20 is lobed and, inthis instance, includes six lobes 34 spaced equidistantly around theperimeter of the disk. Each lobe 34 carries a one-month calendarinterval 24. As viewed in FIG. 1, the uppermost lobe 34a is located at apredetermined viewing location 36 while the lowermost lobe 34b iscaptured between abutment means shown in the form of a pair of parallelabutments 38 projecting from the frame 12 generally parallel to the drum30 and extending along the frame generally parallel to complementaryedges 39 of the lowermost lobe 34b. In this manner, the current calendarmonth is located and retained at the predetermined viewing location 36.

Disk 20 is retained upon drum 30 by a relatively thin lip 40 extendinglaterally from the drum in a radial direction to overlap the disk alongthe perimeter of the aperture 28 so that the disk 20 is secured betweenthe lip 40 and a boss 42 on the pedestal l6.

Disk 20. is fabricated of a resiliently flexible material such as, forexample, Bristol board or a like paper stock. Other suitable materials,such as synthetic resins, will be apparent to those skilled in' the artof materials. The resiliently flexible characteristic of the diskmaterial enables the lowermost lobe 34b to be lifted manually frombetween the abutments 38 so that the disk 20 may be rotated upon thedrum 30 to index the disk to another selected position for locating aselected calendar month at the viewing location 36. Since the months arelocated in consecutive clockwise sequence around the perimeter of thedisk the disk merely need be rotated through 60 of counterclockwiserotation to bring lobe 34c and the next consecutive month to thepredetermined viewing location 36. Upon such rotation, the lobe 34d,which is next in sequence to the previously captured lowermost lobe 34b,will be deflected out of the plane of the disk 20 as the leading edge39a of that lobe 34d engages a ramp surface 44 on the adjacent abutment38 so that the next consecutive lobe 34d will ride over the adjacentabutment 38 and then drop back into the plane of the disk 20, once thelobe 34d is completely between the abutments 38, to capture the lobe 34dbetween the abutments 38 and secure the next selected uppermost lobe 340at the predetermined viewing location 36.

As best seen in FIG. 4, the lip 40 extends radially only a shortdistance beyond the inner peripheral edge 46 of the aperture 28 of thedisk 20 sufficient to retain the disk in place upon the surface 32 ofthe drum 30. However, the overlap is held to a minimum so that theflexible nature of the material of the disk 20 enables the disk to beremoved from the drum 30 by pulling the disk in a direction parallel tothe drum surface 32 to force the disk 20 over the lip 40 and off thedrum 30. Likewise, the disk 20 may be placed on the drum 30 by pushingthe disk over the lip 40 and onto the drum surface 32. The resilientlyflexible nature of the material of the disk, coupled with the relativedimensions of the lip 40 and the aperture 28, enables selective removaland replacement of the disk with ease.

In the illustrated embodiment, the disk 20 carries one full calendaryear and would be replaced each year. Six months of the year are printedupon the obverse surface 22, while the remaining 6 months of the yearare printed on the reverse surface 48 of the disk 20 so that once duringthe year the disk is removed from the drum 30, reversed, and thenreplaced on the drum.

Drum 30 is provided with a relatively large diameter; that is, theoutside diameter of the drum surface 32 is preferably of the order ofmagnitude of approximately one-half the overall outside diameter of thedisk 20. The relatively large diameter of the drum 30 enables a displaysurface area 50 to be located on the frame in a relatively conspicuouslocation so that the display surface area, which is bounded essentiallyby the drum surface 32, may be viewed along with the obverse surface 22of the disk 20. The relatively large display surface area 50 then can beprovided with aesthetically appealing decorative effects, advertisingcopy or other information. Thus, the calendar construction of theinvention provides not only a functional calendar which can becontinuously up-dated for years to come, but provides, as well, aconspicuously located surface area for the display of advertising copy,general information, monograms, or decorative designs. The lobedconfiguration of the disk 20 adds to the aesthetic appeal of the overallcalendar construction.

The frame 12 may be either stored or transported, such as by mail, in aflat configuration, as illustrated in FIGS. 2 and 3, and may then beerected for use as a desk top calendar as illustrated in FIGS. 1 and 4.The frame 12 is advantageously fabricated in a unitary structure ofplastic material, one such material being polypropylene. Other suitableplastic materials will become apparent to those skilled in the art ofmaterials. The use of such materials as polypropylene enables the base14 to be connected to the pedestal 16 by means of an integral plastichinge 52 which includes thin sections 54 interconnecting the base 14with the pedestal 16. These thin sections 54 permit the plastic to bebent or folded along the line defined by the thin sections. The base 14is beveled along the surface 56 and the pedestal 16 is likewise beveledalong a corresponding surface 58 so that the pedestal 16 may be pivotedfrom a first position, wherein the pedestal and the base lie flat andgenerally coextensive (as FIGS. 2 and 3), and a second position, whereinthe pedestal is erect and projects vertically upwardly almostperpendicular to the first position (as seen in FIGSL' 1 and 4).Projecting upwardly from the beveled surface 56 is a detent projection60 which is located in a position to engage a detent shelf 62 runningalong a slot 64 in the corresponding surface 58 of'the pedestal 16 tolock the pedestal in the erect position. Thus, the calendar may bepackaged and mailed or otherwise shipped or distributed in a convenientfiat configuration and is readily erected for use.

It will be apparent, from the FIGS. 2 through 4, that lthe calendarframe 12 is easily molded in one piece in a relatively simple mold andtherefore can be fabriicated in large numbers at an economically lowcost.

Calendar 10 optionally may be used as a wall caleniiar rather than adesk top calendar. Thus, the pedestal ll6 is provided with a recess 66having a keyhole slot 68 contiguous with the rear surface 70 of theframe 12. The frame 12, in the flat configuration, thus may be hung upona wall by a nail or other fastener (not shown) which will be anchored inthe wall and will pass through the keyhole slot 68.

1 The base 14 is also provided with a display surface area 72 upon whichmay be placed advertising copy, other information or decorative effectsand the like. Other types of bases may be employed where specialcalendar locations are desired. For example, a base of the typedescribed in US. Pat. No. 3,469,336, may be utilized where a calendarconstructed in accordance with the invention is to be attached to atelephone.
